THOMAS MCGUIRK AND ORN COLE, OF MILLVILLE, MASSACHUSETTS.

Letters Patent No. 59,919, dated November 20, 1866.

SPECIFICATION- TO ALLWHOM IT MAY CONCERN: p

Be it known that we, VElnonras M cGUIRK and ORIN Conn, of Millville, inthe county of Worcester, and State of Massachusetts, have invented certain new and useful improvements in Carding Engines, and that the following is a full, clear, and exact description of the same, reference being had to the accompanying c irewing,` in which- Figure 1 represents a side view of some of ``the principal parts of two car-ding engines with` our iniprove.- ments applied thereto; and

Figure 2 represents a plan of the same. u

Carding engines, for carding wool for spinning, are generally used in sets of three, which arecommonly' called the first breaker, the second breaker, and the nisher. 4The iirst of these operates directly upon picked wool, the second operates upon the long rolls produced by the iirst, and the third upon the long rolls produced 'by the second. The wool is delivered by the third in a series nf narrow fillets which areV condensed into rcvings,

and the deliveryl is effected by means of doing cylinders having narrow ringsof card-teeth, or ring doifers, as they are frequently called.` In order to save the labor and trouble of applying a seriesof the long rolls produced by one carding engine to the next in the set, an automatic feed 4apparatus has been devised to take the long roll produced by the former, and Aapply it crosswise in alternately opposite directions, and in continuous succession, to the feed apron of the-latter..A When such feeding apparatus is employed for the finisher, the-outmost iillet delivered at each side thereof by the ring doifers has been found too-be of `such variable` or smallsize, that the .roving condensed from it is unfit for spinning with the others; consequently the outside rovings have been thrown aside as waste, and have been taken to the picker by hand, to be repicked and mixed in with'new wool. The object of our invention is to save the labor, trogble, arid-expense of removing these waste rovings, i

and carrying them to and fro by hand; and it consists of the combination of the doifer that takes the outer.- most fillet from the finisher, and some one of the carding cylinders of the'set of carding engines (say of the first breaker or of the second breaker) with conveying mechanism, which we call a creeper,.and which takes the waste rovingor flllet, and delivers it continuously to the carding cylinder, so that it is mixed up with the new wool as fast as produced, thus requiring neither trouble nor hand labor to dispose of it;`

The mode in which we prefer to carry our invention into practical e'ect will be understood by reference to the accompanying drawings, in which A represents the maincarding cylinder of a finisher, and A1 the main i cardng cylinder of a second breaker working in connection with the finisher. Each of theseicarding engines is supposed to be 'fitted with the usual complement of feed rollers, licher-in, workers, strippers, fancy cylinder, doifer or-doifers, and other customary appurtenances, the finisher having two ring 'doiershB B', as is custom-` ary, and being provided with ccndensers, which may consist of 4sets of rubbing rollers C C', condensingtubes,

or other suitable apparatus. The two c ardiug engines are supposed to be connected by the automatic feeding apparatus, which, being well known to builders of carding engines, has 'notbeen represented in the drawings, and need not be described; but which receives the continuous. roll delivered by the second breaker, and applies it to the feed apron of the `finisher in'the usual manner. In the examplerepresented in thevdrawing, the carding cylinder to which the, waste' is delivered is the main cylindert of the second breaker, and in `order to carry away the Voutside rovings or fillets delivered by the ring do'ers of the finisher, a conveying apparatus is used for the outer roving or fillet at each'side'of the finisher.

Each conveying apparatus is composed, in the example represented Ain the drawings, of two creepers, consisting of endless belts and their appurtenances, one of these belts,`D, extending horizontally along the ioor, beneath the carding engines, to the vicinity of the main cylinder, A', to which the roving is to be delivered, while the other, D', extends from the 'delivery end of the first upwards, in an inclined direction, towards the main cylinder A.v These endless belts are supported upon suitable pulleys, a a a a, and are caused to move at about the same speed as that at which the rovings are delivered from the finisher, by means` of suitable shafts, belts, andI belt pulleys, the last belt being applied to a belt pulley Vconnected with one of the carding engines, `soas to move in conformity therewith. The roving or iillet delivered bythe outer ring of one' of the do'ers, B', is taken to i the end of this conveying mechanism, and is applied to it by means of a loose pressing roller, e, which rolls 'by friction upon the surface of the horizontal belt. The horizontal belt carries the roving to the inclined belt D',

which, in turn,"carries it to the main cylinder, A-, of the second breaker; so that when the roving orfelt is once applied thereto, it is continuously taken up by this carding cylinder and mixed in with the new Wool deliv: ered by the licker-in. At the junction ofv'the two belts ive find it expedient to place a second pressing roller e', to keep theroving in itsplace. The journals of both of the pressing rollers are arranged to work in the slots of standards, so that the rollers can accommodate their positions to variations in the roving.

Thev conveying apparatus at the'other side of the finisher is constructed inthe same manner, and receives, conveys, and delivers the outer roving delivered by :theloutermost ring (of thel doffer) at that side of the finisher; and, as it is customary to place the same number of" rings upon each doffer, the conveyingvap'paratus at one side of the finisher in such case acts upon the roving delivered by one doing cylinder, and the conveying apparatus at the otherrside acts upon that delivered by the other dong cylinder. p

The apparatus thus described effects the delivery of the waste rovings or fillets to the main carding cylinder of the second breaker,but by extending the conveying mechanism it might be arranged to deliver the waste tothe main carding cylinder of the first breaker. 0r, in place of delivering the waste directly to the main carding cylinder, the conveying mechanism may be modified to deliver it to one of the other carding cylinders 'of either machine, or to drop it upon the feed-apron; in either of which cases it is passed to the main carding cylinder v,and recarded with the other wool. Moreover, instead of using the outer doier rings of the ring d'oiiers to take the strands from the finisher," special narrow doi'ers may be used for the purpose.

Having thus described the best mode in which wehave thus far embodied our improvements, whatwe claim as our invention, and desire to`secure by Letters Patent, is-

The combination of the do'er of the' finishing carding engine with one of the carding cylinders and a A conveying mechanism, the whole operating substantially as set forth.

In testimony whereof we have hereunto set oui' hands this rst day of June, A. D. 1866.
